A 15-year-old boy is behind bars and facing four felony charges in connection with a shooting in Petaluma. The shooting happened late Monday afternoon. A witness says they saw two vehicles parked next to each other, then heard a loud bang before both sped off. Police don’t think anyone was actually hit with the bullet. The teen boy is facing the charges of assault with a deadly weapon, robbery, negligent discharge of a firearm, and being a felon in possession of a firearm. Petaluma police say the shooting was not a random act.
